5th definitive issue on the stamps of Russia, 17th and 19th issues.
Russian Post in China was a postal service organized by the government of the Russian Empire on the territory of China and operating from 1870 to 1920.
In order to improve postal exchange with China, to ensure the work of Russian consulates, trade missions, private firms, and later the normal functioning of communications in concession territories, Russian post offices began to open from the late 19th century.
According to the opinion of the State Council, highest-approved on March 23 (April 4), 1870, the Russian Post in China was established as a private enterprise under the patronage of the Russian government and receiving from it a subsidy of 17,600 rubles per year. The Russian Post operated between Kyakhta and Tianjin, and along this route four Russian post offices were established: in Urga, Kalgan, Beijing, and Tianjin. These offices accepted and dispatched all kinds of correspondence to all parts of Russia and beyond its borders.
At the beginning of the 20th century, such offices existed in Xinjiang (Chinese Turkestan), Mongolia, Manchuria, the Chinese Eastern Railway, and in a number of Chinese ports (Tianjin, Chefoo, Shanghai, and others).
To pay for correspondence, both stamps of the Russian Empire and special issues for postal items in China were used. Such stamps bore the overprint "China" and until 1917 were used at the exchange rate of 1 ruble = 1 Chinese dollar (yuan). Due to the onset of inflation, from 1917 the stamps were used only in Chinese currency.
By agreement with the Soviet Government of Russia, Russian post offices in China were closed in December 1920 to January 1921.
